Abstract: 1,229,418. Printed circuit assemblies; resistors. JOSEPH LUCAS (INDUSTRIES) Ltd. 25 July, 1968 [3 Aug., 1967; 27 Feb., 1968], Nos. 35748/67 and 9391/68. Headings H1R and H1S. A thin film circuit is produced by anodizing an aluminium plate, heating the plate to stress relieve the anodic layer, depositing resistive and conductive components on the anodized aluminium and annealing the circuit to stabilize the resistive components. Aluminium plate 11, after etching, is anodized in a chromic acid bath to form anodic layers 12 and then washed and heated for ten minutes at 400 C. to stress relieve the anodic layers 12. An apertured steel mask 13 is pressed on to the substrate 11 and a nickel chromium alloy is vapour deposited on to the mask 13 to form resistive deposits 14, 15a on the anodized surface 12. A second mask 17 is then placed on the substrate after a hole 16 has been made in the upper anodic layer 12 and nickel is deposited to form a conductive component 18, nickel areas 14b, 15b on top of the nickel chromium areas 14a, 15a, and a conductive region connected to the aluminium layer 11. A capacitor is thus formed between area 19 and a suitable area 18 on the substrate. The resistors are stabilized by annealing at a temperature of 300 C. for 30 minutes and transistors and diodes are soldered or ultrasonically bonded to the circuit.

Abstract: 1,232,973. Fuel injection pumps; fuel injectors. BRITISH INTERNAL COMBUSTION ENGINE RESEARCH INSTITUTE Ltd. May 28, 1968 [June 5, 1967], No.25879/67. Headings F1A and F1B. A fuel injection pump piston 5 is connected to a piston 4 which is hydraulically actuated. The cylinders 6, 3 are formed in a cylindrical housing 1 which is rotated (as shown) in a casting 2 to act as a rotary valve or is surrounded by a rotary sleeve valve. The housing 1 has ports 8 which register in turn with a port 7 connected to a supply to actuating liquid which may include an accumulator and may be the feed pump (as shown) or a separate supply. Ports 9a, 10 and valve 11 control the fuel supply to the cylinder 6, the supply pressure also causing the return stroke of the pistons 5, 4. A port 12 distributes to outlets 13. The piston 5 has grooves 14, 16 and a passage 15 so that following closure of the port 12 by piston 5 the port is opened to a spill passage 19 connected through a controlled lift valve 21 to a throttle outlet passage 20. The return stroke of the piston 4 and hence the quantity of fuel delivered is regulated by a spring-loaded throttle valve 23, Fig.2, in a discharge port 22 to which the ports 8 open. Operation is controlled by a lever connected to a spindle having a segment 26 engaging the end of the valve 23 which may be forced against the idling stop 29 or completely closed. In a function embodiment Figs.6, 7 (not shown) a spaced control valve and a torque control valve automatically control the port 22 in response to pressure in the passage 20 which varies in accordance with speed. These valves may instead control the flow from the inlet 9 to the pump cylinder. Pressure liquid from the cylinder 6, after the outlet 12 is closed, is fed via passage 63 to a groove 54 which is opened to a port 51 which communicates in turn with pipes 49 leading to the injectors above the valves so that the pressure closes the valve. Subsequently the pipes 49 are relieved to the passage 20 through a valve 59. Two suitable injectors are described Figs.4, 5 (not shown). The timing of injection is controlled by a helical slot drive coupling controlled by a piston 67 having a relief groove 80 and subjected to the pressure in the passage 20. Leakage is discharged by the piston 4 through a valve 58.

Abstract: 1,257,170. Colour television recording and playback; amplitude modulation. INTERNATIONAL BUSINESS MACHINES CORP. 23 Dec., 1968 [26 Dec., 1967], No. 61115/68. Headings H3R and H4F. Recording.-In a colour video recording system the composite video signal input (a), Fig. 1, is frequency modulated on to a carrier (e.g. of 5À5 mHz for an N.T.S.C. system) in a modulator 10, and the frequency modulated signal (d) is amplitude modulated in a modulator 12 by a reference signal (c) which is preferably derived from a phase locked oscillator 16 and a frequency divider 18 as a continuous sinusoidal subharmonic of the 3À58 mHz colour burst signal obtained from the original video signal (a) by a burst separator 14. The amplitude modulated output (e) may then be recorded on a single channel of a recording device, e.g. using magnetic tape. Playback.-Fig. 2 shows the playback system including a first signal channel 22, 24, 26 for removing the amplitude modulation from the recording signal and separating the detected frequency modulated video signal into its luminance and chrominance components by means of filters 28, 30 respectively. A second signal channel 32, 34, 36 extracts the amplitude modulated envelope from the recording signal and by means of a frequency multiplier 38, restores the original colour burst signal frequency. This restored 3À58 mHz reference signal is applied to a demodulator 40 where it recovers the I and Q colour components from the chrominance signal in their proper phase relationships. Amplitude modulation circuit.-Fig. 4 shows an amplitude modulation circuit for use in the recording system, in which circuit the frequency modulated signal from the FM modulator 10 is fed to the base of an NPN drive transistor 50, the output of which is clamped at a junction 52 between serially connected capacitors 54 and 56. The modulating signal, which is sinusoidal, is supplied to a transistor 58 and then to an emitter follower transistor 68. The push-pull signal output obtained from the emitters of transistors 58 and 68 is directed through limiting diodes 70, 72 to the clamped junction 52, where it amplitude modulates the FM signal. The circuit is completed by a driver stage including transistor 74.
